IDEC Relays RH1B-UAC24V Relay

The IDEC RH1B-UAC24V is a high-performance SPDT Relay engineered for heavy-duty switching in compact industrial and HVACR control panels. This IDEC RH Series power relay features a 10A switching capacity with silver cadmium oxide contacts, designed to minimize voltage arcing and ensure reliable operation under continuous load. With a 24VAC coil (operating range of 19.2 to 26.4VAC) and standardized blade terminals, it offers seamless integration for technicians replacing standard midget-style relays. Its miniature footprint optimizes rail density, while the plug-in mounting supports DIN rail, surface, or panel mount configurations when paired with appropriate sockets like the SH1B-05. Built to thrive in demanding environments, this 10A power relay maintains stability across temperatures from -25°C to 70°C, making it a staple for energy management and automated machine control. This electromechanical relay is UL recognized and CSA certified, ensuring compliance with rigorous professional standards for industrial control circuits.

• High Switching Capacity: Reliable 10A resistive load handling in a space-saving midget housing.
• Arc Suppression: Silver cadmium oxide (AgCdO) contacts extend the service life of 24V switching components.
• Universal Mounting: 0.187-inch blade terminals compatible with standard relay sockets for fast field replacement.
• Rugged Design: Excellent vibration and shock resistance (100G damage limit) for high-cycle industrial applications.

What socket is required for the RH1B-UAC24V?
This relay typically pairs with the IDEC SH1B-05 or SH1B-06 series blade terminal sockets for DIN rail or surface mounting.

Can this relay be used for 24VDC circuits?
No, this specific model (RH1B-UAC24V) is designed for a 24VAC coil. Operating it on DC current will result in coil failure; always verify your control voltage before installation.

Is this a direct replacement for other midget relays?
Yes, the RH1B-UAC24V uses a standard terminal arrangement that allows it to interchange with many major competitor 10A miniature power relays.
